The LCD display features both low battery indication and a user selectable backlight. The pH readings are either manually or automatically temperature compensated over the range of 0°C to 100°C. To automatically compensate it is necessary to utilise a thermistor temperature probe.Each unit incorporates a power-off facility that automatically turns the instrument off after ten minutes, maximising battery life. The 430-020 has an integrated rubber seal to ensure complete water resistance and help to reduce the possibility of damage in harsh environments. At the touch of a button the instrument will automatically re-calibrate itself (two-point autocal) when used in conjunction with pH buffer solutions. Each unit incorporates an easy to use BNC connector and Lumberg screw-locking type connector.SpecificationsRangeResolution, Accuracy-2 to 16 pH0.01 pH, ± 0.02 pH± 1000 mV1 mV, ± 1 mV-39.9°C to 149.9°C0.1°C, ± 0.4°C (-10°C to 70°C)Battery3 x 1.5 volt AAABattery LifeMax 5 years (2500 hours)Sensor TypeCombination electrode/thermistorDisplay12 mm LCDDimensions (mm)32 x 71 x 141Weight (g)230Spares/Consumables:pH Electrode for use with 430-020 meter (430-020/10)Spare pH Electrode for use with 430-020 MeterProduct Code: 430-020/10General purpose, epoxy bodied electrode with gel fill solution (maximum temperature 60°C).322WaterEnvironmental TestingPortable Conductivity/TDS Meter with Electrode & Carrying CaseProduct Code: 513-160Dissolved Oxygen/Temperature Meter with Electrode & Carrying CaseProduct Code: 521-050tel: +44 (0)1525 249 200 • email: ele@eleint.co.uk • www.ele.comSuitable for testing either natural and treated water, or waste water and effluents. This portable microprocessor-based turbidity meter provides lab-grade accuracy even in the field. With 4 keys and weighing only 510 g, the meter measures turbidity from 0 to 1000 FTU (NTU). For best field accuracy, it measures from 0 to 50 FTU in steps of 1/100th of FTU. Unlike standard lamps, the infra-red LED has a long life. More significantly, it maintains constant emission for the entire life of the instrument. The wavelength peaks at 890 nm, which provides the required intensity of diffused light even in samples with low turbidity values, and also reduces the interference from any colours. The meter is very easy to use. All operations can be carried out with only four keys and troubleshooting functions can be performed with error code on LCD. Moreover, the meter’s versatility and durability ensure low maintenance. The meter can store and retrieve the last calibration data. At the touch of a key the last calibration data, together with time and date, are displayed, allowing the user to maintain an accurate calibration schedule. Auto shut-off turns the meter off after 5 minutes of non-use to save batteries. The turbidity meter comes supplied with 2 cuvettes, tissues, cleaning solution and calibration solutions for 0 and 10 FTU. ±Easy to use. ±High range. ±Calibration data storage facility. ±Results displayed as FTU. ±Water resistant.SpecificationsRange0.00 to 50.00 FTU; 50 to 1000 FTU.Resolution0.01 FTU (0.00 to 50.00 FTU); 1 FTU (50 to 1000 FTU).Accuracy± 0.5 FTU or ± 5% of reading (whichever is greater)Battery Life60 hours or 900 measurements.
